Vario MAX Cube Large Sample Quantity CN/CNS Elemental Analyzer

vario MAX cube

Small size and excellent performance

The Dumas combustion nitrogen determination method has become a globally recognized standard for the rapid and accurate determination of nitrogen content in agricultural products and other substances. Compared with the wet chemical Kjeldahl nitrogen determination method, the Dumas combustion nitrogen determination method is superior in terms of speed, safety, and environmental friendliness. Representative analysis of natural products requires larger samples weighing 1 gram or more.

ELEMENTAR, a German company, has always been a pioneer in developing organic element analyzers and macro sample analyzers.

ELEMENTAR launched the Macro N analyzer in 1988. It is a combustion type nitrogen analyzer that uses reusable steel crucibles to analyze samples weighing up to 3 grams.

The long-standing design tradition of macro sample analyzers, combined with advanced electronic, software, and robotics technologies, makes the Vario MAX cube a more advanced analyzer in terms of analytical performance, reliability, cost, and analysis speed.

feature

Maximum sample size
CN analysis can be performed on samples weighing up to 5 grams. It can measure absolute carbon and nitrogen content up to 500 milligrams (depending on the mode).

90 bit automatic sampler
A steel crucible that can hold 5 milliliters of solid or liquid, with a service life almost forever. Automatically remove ash content and reload samples at any time (including during operation).

Analysis is lightning fast
Nitrogen determination can be completed in less than 4 minutes (depending on the sample). Will not interrupt operation due to blank and recalibration measurements, achieving high sample throughput.

Best accuracy
For example, beer with a nitrogen content of only 5 ppm or soil with a carbon content of 10 ppm.

Extremely long stability
It can operate automatically all night without human supervision. Only one blank value check is required per day.

Efficient water removal
By using a multi-step condenser and Nafion (R) gas dryer, it can operate for a long time without maintenance and even continuously process a series of 2ml liquid samples.

vario MAX cube CN
A macro sample analyzer capable of simultaneously measuring CN.

This analyzer is particularly suitable for determining protein (N) in meat, grains, feed, dairy products, and beer. In the CN model, typical application areas include plant tissue, soil, manure and compost samples, as well as extracts of these substances.

Adopting reusable crucibles and automatic ash removal technology, it is economical and easy to operate.

vario MAX cube CNS
Vario MAX cube CNS can simultaneously measure CNS.

In the CNS model, typical application areas include plant tissue, soil, compost and fertilizer samples, as well as extracts of these substances.

Adopting reusable crucibles and automatic ash removal technology, it is economical and easy to operate.

measurement method
Burn the sample at a high temperature of 1200 ° C and analyze the resulting gas. Determine nitrogen/protein according to the Dumas method, or determine CN according to AOAC, DIN/ISO, EN, and other international standards.

Easily handle samples
Weigh directly in a reusable crucible (steel or ceramic) without any special pre-treatment. Suitable for solids or liquids up to several grams or milliliters.

Safe, fast, and clean
Analysis only takes a few minutes. No corrosive or toxic chemicals are required. Separate water and carbon dioxide using physical methods.

Wide concentration range:
From ppm to 100%, or 500 milligrams of absolute carbon and nitrogen content (depending on the mode)

Low operational requirements
A 1-meter experimental workspace, 1 power connector, and 2 types of operating gases are sufficient for long-term operation

fully automatic
Equipped with a 90 bit integrated sample changer, via Windows on the PC^®Control instruments, optional software that meets the requirements of 21 CFR 11 regulations.

Electronic microbalance:
The balance and elemental analyzer form a system. We provide microbalances and analytical balances supplied by manufacturers for our instruments.

soliTIC：
Attachment for determining total inorganic carbon in samples.

Upgraded attachment for analyzing total organic carbon (TOC) in solids

Upgraded attachment for determining ash content

Software functionality that meets the requirements of 21 CFR 11 regulations

Our consumables kit includes all the components and chemicals required for the corresponding mode. In most cases, it includes combustion tubes/reduction tubes, all chemical and instrument specific vulnerable parts. We will not compromise on the quality of the components and chemicals we use - this is a prerequisite for ensuring the durability of our instruments.

Provide a consumable kit that can perform approximately 4000 analyses

Small vulnerable parts set:
A practical combination that includes the most important laboratory O-rings and fuses.

Of course, various consumables can also be ordered separately.
